About this item 3-in-1 EMF detector：Accurately detects Electric Fields (EF), Magnetic Fields (MF), and Radio Frequency (RF) radiation. EF mode picks up emissions from household appliances like microwaves and smart meters. MF mode tracks magnetic fields from devices such as motors and power tools. RF mode monitors radiation from mobile phones, Wi-Fi routers, and 5G signals. Precision Without Interference：This EMF meter measures only one field type at a time—EF, MF, or RF—to avoid signal interference and ensure consistently accurate results. Perfect for environments that demand precise EMF measurement. High-Definition Display & Rechargeable Battery：Features a 3.1-inch LCD screen with clear, easy-to-read display. The EMF reader is equipped with a 1200mAh rechargeable battery and Type-C fast charging port. It also includes a 15-minute auto-shutoff feature and a low battery alert to help conserve power during extended use. Sound & Light Alarm：Supports multiple units (V/m, µT, mG, mW/m²), making it ideal for labs, homes, and offices. The tri-color backlight (green/yellow/red) automatically adjusts to radiation levels. When EF exceeds 40 V/m, MF exceeds 0.12 µT (or 1.2 mG), or RF exceeds 10 mW/m², the EMF reader activates an audible and visual alarm (with optional mute) to alert users of high radiation. User-Friendly Operation：Features MAX and Peak modes to help users lock and hold readings for easy analysis and tracking. The mute function allows for silent operation in quiet settings or during ghost hunting, minimizing distractions or false alarms. Package Contents: 1 × EMF Meter, 1 × Charging Cable, 1 × User Manual, 1 × Storage Case. If you have any questions, please feel free to contact us; our professional team will respond promptly.
